' OUTLET 'STRAINER.

Application filed November The Aobject of my invention Iis to provide a vdevice including a strainer and valve or Aplug adaptedto be inserted in outletsnof basins, tubs and thelike, to control the flow of water therefrom and to serve 'asa strainer for the routlet.

In carrying out my invention I provide la base member having afval-ve seat, a perforated casing connected with the base-:and containing a valve. .or .plug to close against said seat, .and a movable memberl supported in position to move said valveor plug from its seat vand Lretain it unseated lfor Istraining purposes and to cause said valve or plug to be seated to close the outlet.

My invention comprises novel details of improvement that will ybe more fully hereinafter set forth and then pointed out in the claims. f

Reference is to be had tothe accompanying dra-wings forminga part Vhereof wherein Fig. 1 is aside view of an outlet strainer embodying my invention;

Fig. 2 is a vertical section ofF ig. 1 showing 'the valve closed;

Fig. 3 is a sectional detail illustrating the valve in open position; l

Fig. 4 is a section on :line 4, 4, in Fig. 2;

Fig. `5 .is a detail `of the valve member;

Fig. `8 vis ia perspective detail of `the valve actuating member; :and i f 7 is a section online 7, 7, in'Fig. 1.

Similarr numerals vof reference indicate corresponding parts inthe several views.

At 1 is indicated a base member shown provided wit-h a tubulafr extension 2 to seat in van outlet 3 of a basin, tub or the like. Extension 2 is shown externally threaded at 4 to mesh with threads in an internally threaded fitting 57 which may be of the character usually inserted in outlets for basins, tubs and the like, whereby the Ibase 1 may be detachably secured in the outlet. The member 1 is provided with a seat 6 adapted to receive a valve or plug 7 to fit against said seatto close the outlet. The valve is guided by means of a stem 8 centrally disposed in the valve. At 9 is a perforated casing or shell attached to the base 1, as by screw threads at 10, so that said parts may be detached. The casing or shell 9 is shown provided with a bore 11 axially disposed and receiving the stem` 8 at the upper portion, the lower end of the stem being shown guided in an aperture 12 in a r4, 19215. serial No. eases.

brace orI spider 1SV that extends "across the tubular .extension 2, whereby 'the valve may be raised and lowered respecting the seat.

About the valve is a tubular piece 7a slid- Y able on steml8 and fto which an enlargement or disk c14 is attached that is spaced `lfromv the upper surface ofthe vaf'lve.v The enlargement 14 rests against :zt-shoulder 7b lon piece 7a andthe outer -end of the Vlatter is irive'ted Over the enlargement to 'retain it. The lstem 8 'has a shoulder 8a against which the .piece 7a 'bears and a nut 8b on the stem bears against the valve rto force it against the piece 7a and kforce the latter against the shoulder 8a, whereby the valve, 'the stem and the. enlargement are secured 'together asa unit. A spring at 215', shown linterposedV between 'the ltop portion of the casing or shell v9 and the enlargement or disk 14, serves normally to press the valve to its-'seat 1 for closing the outlet.

I provide-one `orm'ore projections or camlike members 16 extending Afrom a sha-'ft 17 that is journaled transversely fin the casing or shelll 9, said kextensions .and shaft .being located between valve 7 andvits enlargement 14'. The outer ends -of thepr'ojections .16 are shown vcurved 'fin such .a way as Eto operate against kthe ien-largement 14 for raising the valve from 'the seat.'v 'llhe shaft may 'be journaled in .the casing or shell by means ofY pivots 18, 19 which may be passed through journal 'holes `in the .casing :and into corresponding bores `in the ends of the shaft afterv the 'flatter has been inserted within the `casing'9, ig. The shaft is provided with an operating member or handle 2O located along the exterior of casing 9 and shown secured to the pivot 18, whereby shaft 17 may be rotated. The projections 16 are 95 preferably spaced apart on opposite sides of the stem 8 to cooperate together with the enlargement or disk 14 for operating the valve in a balanced Way, so that substantially equal lifting eliect will be applied to 100 lthe valve on opposite sides of the stem when shaft 17 is rotated to unseat the valve. By preference one side of the shaft 17 is reduc-ed or cut away at 17 a, at theportion over the valve or plug 7, so that when the shaft is rotated to raise the valve from its seat the latter may enter the reduced portion 17a of the shaft, as indicated in Fig. 3, with the valve opposing the shaft, whereby the flat surface of the reduced portion 17a of the 110 shaft. Will engage the valve, serving to keep the shaft from rotating reversely to close the valve on its seat unless manually oper ated. The operating member 2O may be connected With a chain extending Without the basin or the like for manipulating the valve Without requiring the operator to put his or her hands in the Water in the basin.

In accordance with my invention the base 1 may be attached to an outlet for a tub or the like in the manner indicated in the drawings, and in such a position that the perforated casing or she-ll 9 Within the basin will act as-a strainer and also a pro-tector of the valve. When it is desired to use the valve as a stopper the shaft 17 will be appropriately rotated so that its projections 16 will operate from the position shown in F ig. 1, wherein the valve 7 is shown in the open position, to the position shown in Fig. 2, wherein the valve is in the closed position, so that the basin or the like may be charged With Water as much as desired. `When the Water is to be drained the shaft 17 is rotated reversely to cause its projection 16 to raise the valve from its seat and the flat surface 17L of the shaft will engage the upper surface of the valve and retain the valve in the open position. The spring 15 't serves to force the valve to its seat when is of advantage although the device is operable Without the spring.

Changes may be made in the details of construction set forth, Within the scope of the appended claims, Without departing from the spirit of my invention.

Having now described my invention What I claim is:

1. A device of the class described comprising a base having a seat, a perfo-rated casing secured to the base, a valve to close against the seat, and an operative member for the valve movably supported by the casing above the valve to unseat the valve.

2. A device as set forth in claim 1, in which the operative member includes a shaft provided with one or more projections and the valve is provided With means cooperative With the projections to unseat the valve.

3. A device of the class described comprising a base having a seat, a perforated easing secured to the base, a valve to close against said seat, means for guiding the valve for movement toward and from the seat, a valve operating member inovably carried by the casing for raising the valve from the seat, and means exterior to the casing to actuate said member.

il. A device as set forth in claim 3, in which the operating member comprises a shaft journaled upon the casing and provided With one or more projections to actuate the valve.

5. A device of the class specified compris ing a base having a seat, a valve to close against the seat, an enlargement spaced from the valve and connected thereto, means to guide the valve for movement to- Ward and from the seat, and a shaft jour! naled transversely of the device and provided With one or more projections, the shaft and its projections being located between the valve and its enlargement for actuating the valve.

6. A device as set forth in claim 5, in which the shaft is provided With a reduced portion on one side adapted to oppose the valve when the latter is retained unseated by the said projections.

7. A device as set forth in claim 5, provided With a spring located between the casing and the enlargement to force the valve to its seat When the shaft has been sufficiently rotated from the position lfor retaining the valve open.
